These are the UL94 ratings of the base resin used to make Coex Flame Retardant ABS filament. They are not ratings of a finished printed part. How a printed part performs depends on its geometry, wall thickness and print settings, so test parts for your application. The UL yellow card is available on request.
Ventilation is required
Use direct ventilation. Vent outdoors, or through HEPA and carbon filtration.
Never let Flame Retardant ABS cool in the nozzle. Remove it while the nozzle is still hot, then purge with standard ABS.
